I am so glad I found this place. I have a question to you all about Pilonidal cyst. My 17 year old daughter started complaining of tailbone pain 10 days ago. She said it felt like a bruise and it hurt to sit. Then a few days later she got a large hard painful lump beside her butt crack. Its not on her butt crack but right beside her butt crack on her butt cheek. I took her to the er last night and the dr thinks its either a cyst or an infection. He did not think it was a Pilonidal cyst because in was not on the tailbone but to the side of it. She does have a very small pit in beside the lump but its very small and you can only see it if you spread her cheeks apart. And it does not look like it is an open pit. (Its very small). Now my question is : What do you all think this could be if it's not a pilonidal cyst. I think it is pilonidal cyst but I'm not a dr. And are the lumps /bumps hard???? Can you still have a Pilonidal cyst if the lump is not on your butt crack/tailbone????? Can anyone help me????? I'm really worried!!!! I worry about cancer all the time. Thank you mari oh ya I forgot to mention that the doctor put her on some antibiotics which don't seem to be helping .
